i just hooked up one kendwood 9105d/alpine swr1222d @ 1ohm. I am using a (audiopipe high/low converter & 4gauge audiopipe amp kit) connected to factory stereo. after completing installation i had about 2hrs of playing time without any issue. now all of a sudden when my music is playing the bass just surges loudfor about 8secs at most, 3 secs atleast. (it sound like when your testing your subwoofer using one low frequency), and even if i turn the volume down it still happens at varying times. does any one knw whats causing this. can someone help please. all items are fairly new.
